Savings and Payback
The payback period obviously depends on the cost of the turbine and installation as well as the amount of energy generated. Further, since the market is still relatively immature there is little real data available. However, payback periods are estimated to be around 10 or more years.
- Energy and Carbon savings
A 6kW system can provide 12,000-15,000kWh or units of electricity, reducing carbon dioxide emissions by 5-7 tonnes per year.
To increase the cost-effectiveness of the turbines and the amount of energy saved, a method of energy storage, such as an electric immersion heating element in a water tank, should be used. This will help ensure that all of the electricity generated by the wind turbine is matched by the load of the household.
Typically, a household sees a reduction of between a quarter and a third in its annual electricity bill.
